Medical Xpress / Motherhood leaves lifelong brain marks via dopamine-linked epigenetic switch, mouse study suggests
Becoming a mother changes the brain not just temporarily, but for life. Pregnancy and the postpartum period trigger lasting changes in the maternal brain through the brain chemical dopamine, producing long-term benefits to ...
Phys.org / New gold-palladium catalysis mechanism could advance bio-based chemical manufacturing
The building‐block chemicals behind everyday products—like shampoo bottles, food containers, and kitchen spatulas—are largely derived from oil. Researchers are now working to replace those fossil‐fuel‐based inputs with materials ...
Phys.org / Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study ...
Phys.org / Moms' learned fear of snakes gets inherited by offspring in a critically endangered mouse, biologists discover
Conservationists often raise the young of endangered species in captivity before releasing them into suitable habitats as adults. The benefits are obvious: survival to adulthood is typically high, as captive animals are safe ...
Medical Xpress / Summer sun fails to fix vitamin D gap in at risk groups
Vitamin D levels remain low all year-round in key at-risk groups in England, challenging the belief that summer sunlight is enough to restore them.
Medical Xpress / Even years after stroke, spinal cord stimulation could improve arm function
University of Pittsburgh School of Medicine researchers report the final outcomes of a pioneering pilot clinical trial using electrical stimulation of the spinal cord to improve arm and hand mobility in people with chronic ...
Medical Xpress / Popular GLP-1 drug may slow down biological aging, analysis indicates
Glucagon-like peptide-1 (GLP-1) receptor agonist medications have gained widespread attention for effectively treating obesity, lowering blood sugar and decreasing the risk of cardiovascular disease. Some researchers have ...
Medical Xpress / After early pregnancy loss, 'what if' thinking affects 72% within first week
When a person goes through a traumatic experience, they often find themselves thinking that what happened could have been different or even avoided. This process, known as counterfactual thinking, is an automatic psychological ...
Phys.org / Japan's new seafloor record could sharpen megathrust earthquake warnings in Nankai Trough
Off the southern coast of Japan, the Philippine Sea Plate lies underneath the Japanese mainland. The locked tectonic plates threaten to unleash a catastrophic megathrust earthquake, likely within the next few decades. Given ...
Phys.org / A giant star may have destroyed itself in one of the universe's rarest explosions
Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving ...
Phys.org / How Jupiter may have redirected life's ingredients toward Earth 4.5 billion years ago
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution ...
Medical Xpress / How aging reshapes sensorimotor learning: Older adults may lose explicit strategy but gain implicit adaptation
When most humans reach late adulthood, their ability to coordinate movements and maintain balance, broadly referred to as motor control, tends to gradually decline. While these changes in motor control are widely documented, ...
